LUBRICATING DEVICE.

Specification of Letters Patent.

Patented Apr. '13, 1920.

Application filed November 4, 1919. Serial No. 335,690.

To all whom it may concern Be it known that I, RICHARD A. BATES, residing at Berwick, Columbia county, Pennsylvania, and being a citizen of the United States, have invented certain new and useful Improvements in Lubricating Devices, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and to use the same, reference being had to the accompanying drawings, which illustrate the preferred form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof within the scope of the claims will occur to persons skilled in the art.

In said drawings: a

Figure 1 is a central longitudinal. section of view taken through the lubricating device forming the subject matter of the present invention. I

Fig. 2 is an inverted view of the structure shown in Fig. 1, that is looking from the interior of the lubricant chamber.

Fig. 3 is a transverse sectional view th section being taken on line 3--3 of Fig. 1.

Fig. 4 is a view taken partly in vertical section and partly in side elevation on the.

line 4 -4 of Fig. 1.

Fig. ,5 is a view taken on the same section as Fig. -1' withthis difference that whereas the parts are shown in assembled relation in Fig. 1 they are shown in Fig.-

Another object is to provide a device of. the character described, which, due to the conformation of essential parts automatically locks itself in position where applied, thereby dispensing with the customary secured threaded portions heretofore in vogue, which are separable in service due to vibration and from other causes. The device comprises but few simple and rugged parts which are economically produced and 2' is automatically locked in position.

I applied to said -cant in which a lubricating chamber indicated generally at 7 is formed therein. This body is perforated as shown and in the perforation is seated a plug 8 comprising a flanged head portion 9 equipped with a valve seat 10 and a hollow inwardly extending .sleeve 11,which latter is formed with a plain exterior and relatively smooth surface as distinguished from a screw threaded exterior surface. The sleeve 11 is provided at diametrically opposite points with seats 12 adapted to receive the bent locking end portions 13 of a locking yoke 14' hereinafter specifically described. In the present instance the seats 12 comprise slots extending. entirely through the wall a of the sleeve 11 and the construction shown is thepreferred construction in that when the parts are assembled as shown the device The yoke 14 extends from the curved end port1ons13 inwardly and the middle portion thereof is formed into a loop 15 of sufficient diameter to permit the passage therethrough of the stem 16 of the valve 17 and intermediate the head 18 of this valve and the head 18 ofthe valve as shown in Figs. 1 and 5, though it is possible to unseat this head asshown in Fig. 4 when it is desired to fill the lubricant reservoir. In Fig. 1 a fragment of the spout 21 of an oil can is shown bearing against the exterior face of the head 18 for the purpose of unseating the valve. Threaded upon the sleeve 11 and intermediate the flanged head 9 thereof and the body 6 is an annular packing 22, the purpose of which is to prevent waste of lubricant in service. In assembling the parts the valve is inserted from the rear or bottom portion of the sleeve as shown after which the spring 19 is threaded upon the stem of the valve and the yoke 14 is 1 stem whereupon the sleeve maybe projected through an orifice into the lubricant reservoir and the parts are so proportioned that when the sleeve has been thus projected longitudinally a sufiicient the loop 15 an expansion spring 19'is interv posed of such length that it normally seats distance the curved portions 13 of the yoke,

which latter is of spring metal, will expandoutwardly within the seats 12 and project beyond the exterior line of thesleeve sufficiently to interlock with the interior face 6 of the wheel or other body to be lubricated and the resiliency of the yoke memher will hold the parts in cooperative engagement in which position the felt annulus 22 will perform its proper function.

Though the parts automatically interlock during assembly they are removable'if desired'and this is readily accomplished by merely driving the valve inwardly a suili-' cient distance to unseat the curved extension 13 of the yoke 14: whereupon said extensions 13 will be retained within the sleeveand the device may be removed. Preferably the sleeve 11 is of such external diameter that a driving fit is secured between it and the member 6 and this plus engagement of the portions 13 with the interior face 6 will effectually prevent accidental displacement and loss of the device in service.

What I claim is: 1. In a lubricating device a hollow flanged I plug provided with-seats intermediate its ends, a locking yoke held in said seats and flanged mediate its ends, a spring supporting yoke having end portions adapted to cooperate with said flange to lock the plug in operative position, a valve and'a spring adapted to seat said valve. 7

at. In a lubricating device a hollow flanged plug provided with seats intermediate its ends, a locking yoke held in said seats and forming a spring seat, a valve having a stem portion extending through said spring seat and a spring on said spring seat. adapted to actuate said valve.

5. In a lubricating device a hollow flanged plug provided with slots intermediate its ends, a locking yoke held in said slots and forming a locking means, a valve movable in said yoke and a spring held by said yoke adapted to actuate said valve.

6. In a lubricating device a hollow flanged plug provided with slots intermediate its ends, a locking yoke projecting through said slots the yoke having a loop formlng a spring seat, a valve movable in said spring seat and a spring bearing on said spring seat and valve adapted to actuate said valve.

7. In a lubricating device a hollow flanged plug, provided with seats intermediate its ends, a locking yoke having curved end portions projecting through and being held in said seats and a spring seat formed by said yoke intermediate its ends, avalve having a stem movable insaid spring seat and a spring on said spring seat adapted to seat said valve.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
